History

History
The element Chlorine was discovered by Carl Wilhelm Scheele in year 1774 in Sweden. Chlorine derived its name from from the Greek word chloros, meaning 'greenish yellow'
The element Silicon was discovered by Jöns Jacob Berzelius in year 1824 in Sweden. Silicon derived its name derived its name from from the Latin silex, 'flint' (originally silicium)
